Ahh, ok.  That makes more sense now, thanks.

Yes, that is what I tried to say here:

As the exit code of 1 is the only way I see to detect an unhandled exception
in the child.

Yeah, it really isn't a huge issue.  It leaves us with the fact that Zope
always reports startup success, even in hopeless cases.  This isn't a real
problem - just a nicety - along the lines of making Zope a first-class
service on Windows <wink>.

I'm happy to let that idea rest.

To your other mail:

I'll attach the patch in private mail.  I just tried attaching it to
collector 1020, but I don't have permission.  It has the redirection and the
sleep fix, but no changes to the startup strategy.

Yes, and it is my fault that code even exists.  As far as I know, win32all
was the only product that registered modules in this way, and later versions
no longer do.  I'd be +1 on getting this removed from Python.
